COIN-CONTROLLED APPARATUS FOR VENDING AERATED LIQUIDS.

SPECIFICATION formingpart of Letters Patent No. 599,355, dated February 22, 1898.

Application filed May 21,1897. Serial No. 637,501. (No model.)

To aZZ whom it may concern: I

Be it known that I, HENRY RAUCH, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Coin Controlled Apparatuses for Vending Aerated Liquids, of which the following is a specification.

My invention relates to liquid-vending coincontrolled apparatuses; and it is especially designed for delivering by the glass in measured quantity an aerated or carbonated beverage.

The object of the invention is to provide a simple and inexpensive apparatus which when a proper coin is dropped in the slot may be made to deliver in a glass or other vessel a measured amount of the carbonated liquid, a part of the invention relating to the measuring devices, a part to the coin-controlled devices, anda part to the means for delivering the liquid while under gaseous pressure into the glass or cup in a proper manner.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is a general side elevation on a comparatively small scale and showing the charged fountain coupled to the apparatus. Figs. 2, 3, and 4 are sectional views of the apparatus on a larger scale than Fig. 1, Fig. 2 being a section on line a in Figs. 3 and 4, Fig. 3 a section on line 00 in Figs. 2 and 4, and Fig. 4 a horizontal section on line 00 in Fig. 2. Figs. 5, 6, and 7 are sectional views of the apparatus on a larger scale than Figs. 2, 3, and 4, showing the mechanism controlled by the coin. Fig. 5 is a section taken transversely through the operating-stem and coinpocket, showing the coin in the pocket and connecting the stem with the barrel 12 5 and Fig. 6 is a section taken transversely through the operating-stem and barrel, showing the means for lifting the pawl 18. Fig. 7 is a vertical axial section through the barrel and operating-stem, showing the coin in the coinpocket. Fig. 8 is a perspective view of the operating-spindle and shell detached. Fig. 9 is an enlarged sectional view of the delivcry-nozzle.

In Fig. 1, X represents any suitable form of easing or stand, and F an ordinary charged fountain, such as those, for example, containing carbonated water and connected with soda-dispensing devices.

A represents as a whole the apparatus embodying my invention. This appusarat will now be described.

1 is a holder having a chamber adapted to contain a measured quantity of liquid-say one glass. As here shown, this holder is supported on the casing Xby a bracket 2. The liquid enters the chamber in the holder by a pipe 3 from the fountain F and is discharged from the chamber by a pipe 4. In the pipe 3 there is a cut-off cock 5, and in the pipe 4 there is a similar cut-off cock 6. To the plugs of the respective cocks are fixed arms 51 and 6, and these are connected by a sliding link 7, adapted to slide up and down in bearings in a box 8 on the side of the holder 1. The plugs of the cocks 5 and 6 are so arranged that when one cock is closed the other is open, and the upper cock is held open and the lower one closed normally by a strong spring 9, Fig. 2, in the box 8, one end of said spring being attached to a fixed part and the other to a prolongation 5 of the arm 5. In Fig. 2 the full lines show the normal positions of the parts, and the dotted lines show the positions when the lower cock is open and the upper cock closed.

To the slide or link 7 is rigidly secured a rack 10, which gears with a toothed wheel 11, fixed on a barrel 12, Fig. 7, which latter has a bearing at its inner end on a stud 1 on the holder 1 and at its outer end in a tubular operating-spindle 13. This spindle has a handwheel 13 on its outer end and a bearing in the wall of the box 8. As seen in Figs. 5, 6, '7, and 8, (the latter most particularly,) the operating-stem has a somewhat semicylindrical shell 14 on its inner end, which shell partially embraces the barrel 12. In the barrel 12 is a longitudinally-arranged slit which forms a coin-pocket 15, adapted, when the barrel is in its normal position, to receive a coin C from a coin-chute 16 in the box8. When the coin is in the pocket, it projects out beyond the outer surface of the barrel 12.

On the barrel 12, adjacent to the wheel 11, is a ratchet-wheel 17, the teeth of which are engaged by a spring-pawl 18.

Now if there is no coin in the coin-pocket and one turns the operating stemor spindle 13 no movement is imparted to the barrel 12, the shell 14 turning loosely or freely about the barrel; but if a coin C be in the coinpocket when the spindle 13 is turned the edge of the shell 14 will strike the coin, which now becomes a controlling part of the mechanism, and through it rotate the barrel 12. The wheel 11 on the barrel being in gear with the rack 10 on the sliding link 7, it follows that the link is shifted and the cooks operated, the

upper cock being closedand the lower cock opened, thus allowing the charge of carbonated liquid in the holder 1 to be discharged at the nozzle N, to be hereinafter described.

As here shown, the operating-spindle is turned to the left and the ratchet-wheel 17 turns under the back-stop pawl 18 and holds the barrel for the time against back rotation. The coin-pocket will now be inverted, and the coin 0 would drop out but for the fact that a lip 14 on the shell takes over it, as seen in Fig. 5, and prevents its falling out. As soon, however, as the hand-wheel on said spindle is released a light spring 19, coiled about the operating-spindle, rotates the spindle back again until a stop-pin 20, Fig. 7, thereon engages a projection or stud 21 on the box 8. When the coin is released by the back rotation of the shell 14, it drops from the coinpocket into the box 8, and in the back rotation of the shell a cam-like finger or projection 22 on the shell 14 takes under and lifts the pawl 18 from the teeth of the ratchetwheel, and this frees the barrel and permits the spring 9 to instantly return the barrel and the cut-off cocks to their normal positions.

It may be Well to explain here that in the operative rotation of the spindle to the left the cam 22 on the shell takes under the pawl 18 from the rear and raises it; but as the cam passes on the pawl is permitted to again engage with the teeth of the ratchet-wheel. Indeed, it is preferable to prolong the cam-finger, so that normally it is under the pawl and holds it elevated.

In the bottom of the box 8 is a drawer 8 to receive the coins that fall from the coinpocket.

It will be obvious that the mechanism of the apparatus maybe inclosed in a casing to prevent its being tampered with by unauthorized persons, only the hand-wheel on the operating-stem and the slit at which the coin is inserted being exposed. In Fig. 1 such an inclosing casing is indicated in dotted lines about the apparatus A.

The nozzle N is seen in side elevation in Fig. 3, and in Figs. 2 and 9 two slightly-different forms of the nozzle are shown in longitudinal mid-section. The form shown in Fig. 9 is preferred. In this construction there is a tapered shell 32, provided with a nipple 33, adapted to screw onto the outletpipe 4. This nipple extends into the shell and has in its inner extension 33 a spring baffle-valve 34, which opens outwardly. Within the shell 32 and inclosing the extension 33 are two concentrically-arranged shells 35, which have perforated side walls. There may be one or more of these shells 35. This device forms what I denominate a muffler and prevents the suddenly-liberated gas-impregnated liquid from being driven out in all directions.

The form of muffler-nozzle shown in Fig. 2 is similar to that described except that the baffle-valve is omitted and the nipple extension 33 is perforated.

It will be obvious that the coin-controlling mechanism may be varied in construction without departing materially from my invention. It is only necessary that the coin shall connect the two mechanisms together while it is in the coin-pocket.

While especially designed for dispensing liquids charged with gas, the invention is not necessarily limited to use with this class of liquids.

Having thus described my invention, I claim- 1. In a liquid-vending apparatus, the combination with a holder adapted to contain a measured quantity of liquid and provided with an inlet-tube at one end and an outlettube at its other end, cut-off cocks in the respective tubes, operating-arms on said cocks, and a link connecting said arms, the cooks being so set that one will be open when the other is closed, of an operating-stem, operating mechanisms between said stem and link whereby the link may be operated when said stem and the operating mechanism are coupled bya coin, and a chute for leading an inserted coin into the coin-pocket of said operating mechanisms.

.2. In a liquid-vending apparatus, the combination with a holder for a measured quantity of liquid, provided with an inlet and outlet, valves 5 and 6, controlling, respectively, said inlet and outlet, operating-arms on said valves, a sliding link 7 connecting said arms, a rack 10 on said link, a wheel 11, in gear with said rack, a rotatiVely-mounted barrel 12, on which said wheel 11 is fixed concentrically, said barrel having in it a coin-pocket of less depth than the diameter of the coin to be used, a ratchet-wheel on said barrel, a pawl adapted to engage said ratchet-wheel, a rotativelymounted operating-stem adapted, in its rotation, to strike a coin projecting from the coinpocket and thereby rotate said barrel, means carried by said operating-stem and adapted to disengage said pawl during the back rotation of the stem, and springs, substantially as described, adapted for returning the barrel and stem to their normal positions, substantially as set forth.

3. The combination with the holder 1, having an inlet-pipe 3, and an outlet-pipe 4, and the cocks in the respective inlet and outlet pipes, provided each with an arm, of a sliding link 7, connecting said arms, a rack 10 on said link, a rotatiVely-mounted barrel 12, having in it a coin-pocket, and having fixed to it a wheel 11, in gear with said rack, and a ratchetwheel17, the pawl engaging the teeth of said ratchet-wheel, the rotatively-mounted operating-stem 13, the shell 14, fixed to said stein and'partially embracing said barrel and provided with a lip 14 and a cam adapted to take under and lift the pawl, and the springs adapted, one to operate the cooks in one direction and the other to rotate the operatingstem in one direction.

4. The combination with the delivery-pipe from the holder, of a niuffler-nozzle comprising a nipple adapted for attachment to said delivery-pipe, a large outer shell fixed to and inclosing a portion of said nipple, and an inner shell between the outer shell and the nipple and inclosing the latter, said inner shell being perforated at its sides, and said outer shell being extended beyond the inner shell, substantially as set forth.

5. The combination with the delivery-pipe from the holder, of a muffler-nozzle consisting of a nipple adapted to be secured to the end of said pipe and provided at its end with a spring-Valve which opens outward, a laterally-perforated shell inclosing the delivery end of said nipple, and an outer, imperforate shell, inclosing said perforated shell, said outer shell being of greater length than the inner shell, substantially as set forth.

6. The combination with the delivery-pipe from the holder, of the outer, tapered shell 32, provided with an attaching-nipple which eX- tends into said outer shell, a baflie-valve 34:, in the end of said extension of the nipple, and one or more perforated inner shells, 35, in the outer shell and inclosing the inner extension of the nipple, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
